The introduction of Pepetools' new Ultra Series Rolling Mills marks the first time in more than 75 years that jewelers' rolling mills are manufactured in the U.S. Pepetools spared no expense in the conception and engineering of the Ultra Series Rolling Mills. Each model was designed to conform to the strictest design criteria. Frames are fashioned from high strength iron so that the total weight of each mill could be reduced to save on shipping costs. Precision machined gear box with large reduction makes it easy to roll metal sheet. Handles are forged from solid steel. Gears are not cast but are hobbed from solid steel. Each Pepetools Ultra Series Rolling Mill comes with a 12 month limited factory warranty. •Roll length: 110mm •Roll diameter: 55.0mm •Flat Section: 54mm wide •Wire Section: 7square grooves, 1.0mm-5.5mm •1/2 round grooves: 3: 4x1.5mm, 3x1.25mm, 2.5x1.3mm •Dimensions: 5.12"W x 11"L deep x 11-1/4"H •Gear reduction: 4:1 •Shipping weight: 45 lbs.
